TECHNICAL FIELD

The present disclosure relates to a fastening device for connecting a runner, such as a drawer runner to a panel, such as a building panel, a wall panel, furniture component or the like.

TECHNICAL BACKGROUND

Drawer sliders are known that are fixed to, e.g., furniture by screws. A drawback with the known systems is that it time consuming to assemble the sliders to the furniture.

The above description of various known aspects is the applicant's characterization of such, and is not an admission that any of the above description is considered as prior art.

SUMMARY

It is an object of certain embodiments of the present disclosure to provide an improvement over the above described techniques and known art. Particularly to reduce the time for assembling and the strength of the locking system is improved by embodiments of the disclosure.

At least some of these and other objects and advantages that will be apparent from the description have been achieved by a first aspect of the disclosure that comprises a set comprising a panel and a slider, such as a drawer slider. The slider comprises a first surface and the panel comprises a second surface. The slider is being configured to be assembled to the panel with the first surface facing the second surface. The second surface is provided with an insertion groove and a displacement groove, which are of a longitudinal shape. A first angle, which is between the second surface and the insertion groove, is an acute angle. A strip protrudes from the first surface and a second angle, which is between the strip and the first surface, is an acute angle. The strip is configured to be inserted into the insertion groove when the slider is assembled to the panel. A displaceable tongue is arranged in the displacement groove and a locking surface of the displaceable tongue is configured to cooperate with a locking surface of the strip for locking the strip to the panel.

The displaceable tongue may be pushed into the displacement groove, by the strip, during assembling of the slider to the panel and spring back to a position in which the locking surface of the displaceable tongue cooperates with the locking surface of the strip.

The panel may extend in a vertical direction and may be a part of a furniture. The strip and the acute angle may have the advantage that the slider may carry a great load when a load, e.g., from a drawer connected to the slider. The slider may comprise an inner part, which is assembled to the panel, and an outer part, which is connected to the drawer. The outer part is displaceable relative the inner part. When the drawer with a load is pulled out and the outer part is displaced relative the inner part a moment is created which may cause the strip to slide out from the insertion groove. The displaceable tongue is intended to prevent that strip slides out from the insertion groove.

A first plane, which is parallel to the depth direction of the insertion groove, may intersect a second plane, which is parallel to the depth direction of the displacement groove.

An opening of the displacement groove is preferably adjacent to an opening of the insertion groove.

The first and the second angle may be essentially the same and in the range of about 45° to about 60°.

A third angle, which is between the insertion groove and the displacement groove, may be in the range of about 60° to about 90°. An angle about 90° may provide an improved locking between the displaceable tongue and the strip.

A fourth angle, which is between the displacement groove and the second surface, may be in the range of about 45° to about 60°.

The locking surface of the strip may be arranged in a recess at an upper surface of the strip.

A locking element may protrudes from the first surface and the second surface may comprises a locking groove, preferably a hole, such as a drill hole, wherein the locking element is configured to cooperate with the locking groove for preventing the strip from being displaced along the insertion groove. The insertion groove may extend along essentially the entire panel and may have an opening at one or both side edges of the panel, e.g., at a backside of the panel. Without the locking element and the locking groove the slider may be displaced along and out of the insertion groove. The insertion groove may also be produced with mechanical cutting with rotating tools with an axis of orientation which is perpendicular to the insertion groove. Such a production may create a rounded surface at an end of the insertion groove. The rounded surface may guide the strip out of the insertion groove when a load is applied on the slider along the insertion groove, e.g., when a drawer which is attached to the slider is pulled out along the slider.

A fifth angle, which is between the first surface and the locking element, is preferably essentially the same as the second angle. A sixth angle, which is between the locking groove and the second surface, is preferably essentially the same as the fifth angle. These angles may provide and easy assembling by a displacement of the slider relative to the panel in a direction parallel to the second angle.

The strip may be provided with a friction connection, such as protruding parts, at an upper an/or lower surface, and/or at an outer edge, wherein the protruding parts are configured to cooperate with a surface of the insertion groove for preventing the strip from being displaced along the insertion groove. The friction connection may be an alternative to the locking element and the locking groove.

Slider may comprise parts comprising a metal, produced of, e.g., bent metal sheets. The slider may also comprise parts comprising a polymer, produced, e.g., by injection moulding.

The core of the panel may be a wood-based core, preferably made of MDF, HDF, OSB, WPC, plywood or particleboard. The core may also be a plastic core comprising thermosetting plastic or thermoplastic, e.g., vinyl, PVC, PU or PET. The plastic core may comprise fillers. The panel may be provided with a decorative layer, such as a foil or a veneer, on one or more surfaces. The panel may also be of solid wood.

The slider may, as an alternative, be a fixed carrying device for, e.g., a shelf or other furniture component.
